To all whom it may concern:

Be it known that I, HUGH PATON, of the city of Montreal, Province of Quebec, Canada, have invented certain new and useful Improvements in Vessel-Covers and Liquid- Shakers; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention has for its object to provide a hygienic. device adapted to rest upon and overlap the edge of a vessel in which liquids are to be shaken, such device being preferably adapted to be temporarily retained in place by atmospheric pressure.

The invention may be said, briefly, to comprise a disk consisting, preferably, of two layers of cork or other like material rendered waterproof and aseptic and a carrier with a central downward convexity upon its interior.

For full comprehension, however, of my invention reference must be had to the accompanying drawings, forming a part of this specification, in which similar reference characters indicate the same parts, and wherein Figure 1 is a top view of my improved device. Fig. 2 is a plan view of the interior with the waterproof disk partly broken away. Fig. 3 is a transverse sectional view taken on line X X, Fig. 2, and illustrating the smaller cover in use and Fig. 4 is a side elevation of a pair of covers arranged one on top of the other.

The disk I have found most serviceable consists of two layers 1) of cork, preferably disposed with the grain of one extending at an angle to the grain of the other. A sheet 0 of fabric is attached to one side of each of the said layers, and a film d of a highly adhesive and pliable substance, such as rubber, is located between the fabric-covered sides which are secured together thereby. The sheets of fabric are first treated to render them waterproof, hygienic, non-corrosive, nonabsorbent, and proof against damage by spirits. This treatment of the sheets of fabric also affects the layers of cork and renders them aseptic.

The carrier I prefer to use is of circular boxlike form 9, and the central portion of the interior of the closed end thereof is convexed, as at h, to provide a protuberance adapted to bear upon the corresponding portion of the disk, while the edge of the latter is free to be pressed into the carrier.

A series of legs 7c, provided with feet m, are secured to the interior of the perimetrical wall of the carrier and actas guides for the disk in its movement when pressedupon the rim of the glass, while the feet retain the disk against displacement from the carrier.

A series of perforations are preferably formed in the closed end of the carrier to enable a decorative device a to be attached thereto, or it might be otherwise secured.

My improved cover is preferably made in two sizes, which when not in use are placed one on top of the other, as shown in Fig. 4.

Then mixing liquids, or stirring a liquid, in a small vessel, the smaller cover is placed upon the rim thereof, and the latter should be held between the second finger and the thumb with the forefinger on the center of the cover. A slight pressure exerted by the forefinger will cause the periphery of the disk to yield and its central portion to be pressed into the vessel by the convexity of the cover. This action has the effect of expelling some of the air from the vessel, thereby creating a vacuum which holds the cover tightly upon the rim and prevents leakage of the liquids at this point however hard the vessel and cover (held as above) may be shaken.

In mixing liquids (or stirring a liquid) in a larger vessel the larger-size cover is used in the same way, except that both hands may be necessary.

The device will be found very useful in the sick-room or in any instance where a vessel containing a beverage, food, or medicine is allowed to stand exposed to the possible deleterious effects of the atmosphere.

The disk is flexible and elastic and can be removed by springing the edge of the same past one of the feet and reversed or renewed at will, and, if desired, other wood or woodpulp may be substituted for the cork if the flexibility thereof be not impaired.

In order to facilitate the removal of the disk, one of the feet m is preferably secured to its leg 7c by a screw-thread connection 7c, and by unscrewing this foot the disk can be removed without bending.

What I claim is as follows:

1. A cover for shaking purposes adapted to be held upon the rim of a vessel by the pressure of the index-finger while the vessel is held in the hand and consisting of a flexible disk, a carrier containing such disk and constructed to, when borne upon by the finger, force the central portion of the said disk into the vessel while the disk rests upon the mm.

2. A cover adapted to rest upon the rim of a vessel and consisting of a carrier having a conveXed interior and a flexible disk supported in such carrier, for the purpose set forth.

3. A cover adapted to rest upon the rim of a vessel and comprising a carrier of circular box-like form with one endopen, the closed end of such carrier having the central portion of its interior convexed, an elastic disk within the carrier, a series of legs secured to the interior of the perimetrical wall of the carrier, and a series of feet upon such legs for the purpose set forth.

4:. A disk for the purpose set forth consisting of two layers of cork each faced on one side with an aseptic waterproof fabric and an adhesive film attaching the said faced layers together.

5. A cover adapted to rest upon the rim of a vessel and consisting of a carrier having a convexed interior and a flexible disk sup ported in such carrier and consisting of two layers of cork with an aseptic film of adhesive substance between them, for the purpose set forth.

6. A cover adapted to rest upon the rim of a vessel and consisting of a carrier having a converted interior and a flexible disk supported in such carrier, and consisting of two layers of cork each faced on one side with an aseptic waterproof fabric and an adhesive film attaching the said faced layers together, for the purpose set forth.

7. A cover adapted to rest upon the rim of a vessel and comprising a carrier of circular box-like form with one end open, the closed end of such carrier having the central portion of its interior convexed, an elastic disk within the carrier, a series of legs secured to the interior of the perimetrical wall of the carrier, and a series of feet upon such legs one of such feet being secured to its leg by a screw-thread connection, for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HUGH PATON.
